▎ 摘  要

NOVELTY - Preparation of polymer composition involves (A) washing, drying, and pulverizing recycled polyolefin to obtain a recycled polyolefin powder, (B) dispersing a filler in the dispersion solution using a bead mill disperser to obtain a filler dispersion solution, (C) mixing the regenerated polyolefin powder with the filler dispersion solution, and (D) adding the resultant to an extruder to obtain a pelletized polymer composition. The filler has an aspect ratio of 10 or more, and length in the longitudinal direction of 0.01-1000 mu m. USE - Preparation of polymer composition. ADVANTAGE - The method improves the properties of the polyolefin, enables the extensive recycling of waste polyolefins, and reduces carbon emission.
